ScandAsia. Indonesia News, 11 October 2012 | news Wachiraporn Janrut

While investigations are pending and the cause of fire on KRI Klewang remains unclear, news about the Indonesian’s stealth warship caught fire on 28 September has raised questions in the Indonesian press about whether the design of the vessel was flawed.

In reply to these speculations, Swedish PT Lundin Industry Invest and LOMOcean Design, builder and designer of KRI Klewang for Indonesian’s Navy, have made a statement.

According to the statement, the design drawings for KRI Klewang were subject to structural plan approval by Germanischer Lloyd in accordance with the High Speed Craft code, so have been subject to intense third party scrutiny by a respected member of the International Association of Classification Societies. Elements of the ship’s design relating to weaponry have also been designed in accordance with the American Bureau of Shipping High Speed Naval Craft (2007) code.

It also states that number of steps are taken during the design and construction to mitigate fire risks and that high fire risk zones on the vessel are treated with a significant degree of fire insulation, which removes the carbon composite materials from proximity to normally hot componentry – and in the event of an outbreak, fire.

The companies believe that the carbon fibre material itself does not contribute significantly to the fire load and the fire was not caused by a lack of design standards compliance and poor implementation of risk mitigation measures such as fire protection and suppression systems.

In the end of the statement, they reinforce that the KRI Klewang project represents a significant step forward by Indonesia in naval technology which opens the door to a bold, new and innovative future.

Jakarta Globe |  October 10, 2012

The makers of a cutting-edge Navy missile boat that was gutted by a blaze last month have stressed that stringent safety measures were built into the design of the vessel and that a combination of external factors were to blame for the fire.
In a letter to the Jakarta Globe, John Lundin, president of Lundin Industry Invest, said the designers of the KRI Klewang recognized that its carbon-fiber hull made it more susceptible to fire than steel-hulled vessels, and took the appropriate measures to mitigate the risk.
“High fire-risk zones on the vessel — which can include engine and auxiliary machinery spaces, galley, weapon locations, etc. — are thus treated with a significant degree of fire insulation, which removes the carbon composite materials from proximity to normally hot componentry — and in the event of an outbreak, fire,” he said.
He added that fire insulation for the KRI Klewang, built at Lundin’s shipyard in Banyuwangi, East Java, complied with International Maritime Organization Safety of Life at Sea conventions and International Classification Society directives.
This includes sheathing electrical switchboards in fireproof insulation and mounting them in fireproof casings, as well as water-cooling engine exhausts.
“There are further protections specifically associated with high fire-risk areas,” Lundin said.
“The machinery spaces can be hermetically sealed once fire is detected; all ventilation shafts have shutters that can be closed and watertight doors also prevent the flow of oxygen required to fuel a fire. Furthermore, all engine rooms were equipped with substantial fire suppression systems able to be activated remotely from the engine room space.”
When the fire, whose cause Lundin said was still being investigated, broke out on Sept. 28, the boat was docked for maintenance and calibration work in preparation for sea trials.
“In this condition, all ventilation hatches for the ship and engine rooms were open and maintenance crew were on board,” Lundin said.
“The presence of personnel in the engine room prevented the full shutdown of the engine room and discharge of automatic systems that would have suppressed the fire; to do so would have resulted in loss of life, because fire suppression gases will not sustain human respiration.”
He said that although the personnel almost managed to put out the fire, “loss of electrical power following the fault meant that these personnel were exposed to difficult conditions of nil lighting and high smoke levels, which forced them from the area for fear of incapacitation.”
He added that the crew managed to evacuate safely, but “was not trained to shut down ventilation shutters and hatches, nor to initiate remotely operated onboard fire suppression systems.”
“In this condition, the fire was able to propagate throughout the interior volume of the vessel,” Lundin said.
He added that the setback should not stop efforts to keep forging ahead with the latest naval technology.
“This ship offered tactical and operational advantages to Indonesia’s Navy that are simply not achievable with traditional shipbuilding materials, benefits that cannot be ignored in the future,” he said.

Warship Composite Construction – Java Shows the Way

By George Backwell at September 08, 2012 07:22
One of the most innovative warships in the world was launched recently, from remote, tropical Banyuwangi on the sea coast of Java, Indonesia, where North Sea Boats has a shipyard. The high-speed littoral waters patrol boat –  to be named KRI Klewang – has a wave-piercing trimaran hull form (offering a very stable weapons platform) constructed exclusively of infused vinylester carbon-fibre composite.

This composite medium was chosen for its multiple benefits including: reduced weight (laminated carbon fibre has a density nearly half that of aluminium alloys) and reduced maintenance (carbon composites cannot corrode and exhibit extremely high fatigue limits). If that were not sufficient justification, this material also provides the nil magnetic signature, reduced thermal and acoustic signatures required to suit the role of this warship.
This fairly remote area of Indonesia lacked the highly skilled specialist workforce with experience in building composite hulls for such an advanced, relatively large vessel – LOA 63m (206.7 ft)  –  in order to achieve the quality required for a build under the eye of classification society Germanischer Lloyd. To overcome this, North Sea Boats introduced its high volume vacuum infusion system to give the necessary confidence in the quality and consistency of the building work.
The flat, faceted panel geometry of the ship itself (the design provides external ‘Stealth’ geometry) also lent itself to this high volume production system, which also employed numerically controlled milling machine technology for the utmost accuracy.
The builders claim that the use of carbon foam sandwich composites on this scale in naval application is unprecedented outside of Scandinavia and is representative of the current state of the art in both maritime composites structural engineering and production technology.
Accommodation is provided for a complement of twenty nine (officers and crew) on three internal decks (including bridge and combat control centre), with facilities and equipment for deployment of special forces troops, including an 11m high speed 50 knot RIB, also manufactured and supplied by North Sea Boats.

Propulsion System

Power comes from multiple MAN Diesel & Turbo V12 diesel engines, coupled to MJP 550 propulsion water jet units which are located in both the centre hull and each of the two side hulls for maximum propulsive thrust and manoeuvrability.

The  MAN 4-stroke power plants each have 12 cylinders in 90° V configuration with four valves per cylinder, water-cooled, plus two- stage exhaust gas turbo-chargers. These engines have common rail electronically controlled direct fuel injection.

The stainless steel water jets, manufacture certified by DNV, come from MPJ Waterjets, part of the Swedish industrial group Österby Marine.

KRI Klewang – General Specifications

LOA 63.0 m (206.7 ft)
Length on Waterline 61.0 m (200.1 ft)
Beam Overall 16.0 m (52.5 ft)
Water Draft 1.2 m (3.9 ft)

More Stories on the KRI Klewang…….First what she was supposed to be !

North Sea Boats launched the first of four advanced, stealthy, 63 meter trimaran patrol boats for the Indonesian Navy on August 31, 2012. Following the completion, extensive sea trials and testing commencing next month, the KRI KLEWANG is is expected to be fully operational 2013. All four vessels are scheduled for delivery by 2014.

The new vessel to be named KRI Klewang (after a traditional Indonesian single edged sword) was launched at Banyuwagni, in Indonesia. Following the official launching the vessel will be fitted with mission systems and weapons, including a remotely controlled gun turret and anti-ship missiles. The four vessels are built at the PT Lundin shipyard in East Java.

The vessel is powered by four MAN V12 diesel engines, driving multiple MJP 550 water jets, located on the three for maximum propulsive thrust and maneuverability. The vessel can develop a ‘sprinting’ maximum speed of 35 knots. Cruising speed is 16 knots and the stated operational range is over 2000 nautical miles.

The Klewang is armed with concealed gun turret, missile launchers and small arms posts. Trimarans offer very stable weapons platforms, and can carry various Missile systems; including Type 705 (up to 8), RBS15, Penguin or Exocet, and 40-57mm Naval Guns, or a CIWC (Close In Weapon System). These can be mounted high on the superstructure, giving better range and firing arc. Sensors can also be installed high up without concerns for stability. This first ship will carry a turnkey system delivered by CSOC and CPMIEC China, including rapid fire CIWS, combat control and missile systems. The exact configuration of this system is still classified.

Accommodation is provided for a complement of twenty nine (officers and crew) on three internal decks (including bridge and combat control centre), with facilities and equipment also provided for deployment of special forces troops, including an 11m high speed 50 knot RIB, also manufactured and supplied by North Sea Boats.

Fire destroys brand new North Sea Boats 63m Stealth Fast Missile Patrol Vessel

A fire destroyed the Indonesian Navy’s

KRI KLEWANG-625 at the naval port in Banyuwangi, East Java on Friday just weeks after its official launch ceremony. The Fast Missile Patrol Vessel (FMPV) was officialy launched on Friday 31st August, 2012 at PT Lundin’s shipyard facility in Banyuwangi, East Java.

See the launch of the vessel at : http://www.youtube.com/watch?v=wSZCQZ5QCPE&feature=related

No casualties have been reported but the brand new vessel worth $12 million USD appears to be lost. The incident reportedly happened during maintenance. Indonesian Navy already announced that they would deploy a team to investigate the exact cause of the fire which lead to the loss of the trimaran vessel. Launched on Friday 31st August, 2012 at PT Lundin’s shipyard facility in Banyuwangi, East Java, the Fast Missile Patrol Vessel (FMPV) employs a modern “Wave Piercing” trimaran design. This allows the vessel to cut-through waves rather than rise up and over them, and the increased beam provides inherent stability. This combination of features reduces both pitching and rolling, creating a stable weapons platform, and enabling the vessel to comfortably and safely maintain higher average speeds in adverse conditions. The FMPV has “Stealth” design characteristics, and incorporate features that minimise detection by reducing Radar, Infra-Red, Acoustic and Magnetic signatures. Stealth properties are further improved as there are no reverse-angle bow overhangs to reflect radar signals, as seen on conventional hull forms. Weaponry, including missiles and naval guns, and the ships 11 m high-speed RHIB, are discreetly concealed or shaped to meld into the superstructure profile. PT Lundin will issue an official statement relating to the incident on Monday.

FIRE ONBOARD BRANDNEW KRI KLEWANG

A report was received that a ship on fire in Banyuwangi, the name reported was KRI Klewang which  was recently launched, and was berthed on the NAVY base ( LANAL ) in Banyuwangi for outfitting. It was reported that the cause of fire cause is a short circuit on engine room.

North Sea Boats launched the KRI KLEWANG as first of four advanced, stealthy, 63 meter trimaran patrol boats for the Indonesian Navy on August 31, 2012. Following the completion, extensive sea trials and testing commencing next month, the KRI KLEWANG was expected to be fully operational 2013. All four vessels are scheduled for delivery by 2014.

Trimaran Fire for the Indonesian Navy

There are a couple of nightmare scenarios for a naval vessel and fire is certainly among them. Our Navy runs countless drills to make sure the crew is ready in case of such an occurrence. While not our guys, this picture of the Indonesian Navy’s KRI Klewang-625 Trimaran in Banyuwangi, East Java is tragic:

A fire raged through the Indonesian Navy’s KRI Klewang-625 at the naval port in Banyuwangi, East Java on Friday at 3:15 p.m. No casualties have been reported but the Rp 114 billion (US$11.91 million) ship was severely damaged. (It’s gone, just a burnt out shell !)

Indonesian Eastern Fleet (Armatim) spokesman Lt. Col. Marine Yayan Sugiana told The Jakarta Post that the vessel was undergoing maintenance by its builder, PT Lundin Industry. “The vessel had yet to be officially handed over to the Navy. It was still undergoing maintenance checks by PT Lundin Industry,” he said.

The navy, however, said it would investigate the blaze, which lasted for two hours before fire fighters managed to extinguish it. “We will deploy a team to investigate the cause of the fire. We will use the report to evaluate the case,” he said.

PT Lundin Industry’s director, Lisa Lundin, said the company would deliver an official statement relating to the incident on Monday.

The good news is that there were no deaths aboard. The bad news is no more ship.

Navy trusts local shipyards despite accident

The Indonesian Navy says it will still rely on the domestic shipbuilding industry despite the fire that severely damaged locally produced KRI Klewang-625 on Friday.

The Rp 114 billion (US$11.91 million) vessel, made by local shipyard company PT Lundin Industry, caught fire when undergoing maintenance at the naval port in Banyuwangi, East Java.

The Tanjung Pinang Naval Base (Lantamal IV) commander, Commodore Agus Heryana, said on Sunday that the Navy would still use local shipyard PT Palindo Marine, which is currently constructing four missile boats.

Agus added that the Navy had not as yet increased monitoring of the Batam-based company to prevent such accidents from recurring. “The Navy has yet to deploy personnel to assist in ship construction. Everything remains normal here,” he told The Jakarta Post.

PT Palindo Marine has been commissioned to build four KCR-40 vessels to support the Navy’s weapons defense system. Two of the vessels, KRI Kujang 642 and KRI Clurit 641, were handed over to the Defense Ministry on Feb. 26 and April 25, respectively.

PT Palindo Marine is also building a 60-meter-long patrol vessel for the Marine Security Coordinating Agency (Bakorkamla).

PT Palindo Marine is one of many shipyards in Batam, Riau Islands. Batam’s shipyard industry grew significantly after the arrival of Singapore-based shipbuilders. The neighboring country has banned the operation of shipyards inside the country due to environmental concerns.

There are currently 90 shipyards across Riau Islands, with 71 percent of them located in Batam. The province’s shipyard industry is estimated to be worth US$3 billion. (yps/lfr)
